Samsung 840 500GB SSD Review - Benchmarks - Sequential Performance

A number of next-generation SSDs are coming to TweakTown this week. OCZ, Intel and Samsung and others will follow after CES. Today Chris tests Samsung's low-cost 840 with TLC flash in the 500GB capacity size. Does TLC show the love or is this low-cost offering another low-budget blunder?

HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.

The Samsung 840 delivers a big dose of low queue depth sequential read performance. It's not just out there; it's way out there - over 30 MB/s faster than the Neutron GTX.

The Samsung 840 is handicapped by TLC flash that has higher latency than MLC flash, a recovery from access times is unlikely, but let's take a look and find out.
